Trashy women think their bodies are much better than they really are and display a lot of skin, usually muffin top / fupa. They also wear gaudy skimpy clothes, usually too tight to draw attention to themselves. Tattoos can also be part of this.
At work theythinkthey should be running the place after 3 days on the job and in spite of being complete fuckups.
Trashy people people are loud, boastful and have foul mouths in an effort to draw attention to themselves and sound tough.
Trashy people are selfish and not team players. Their only goal is to satisfy their needs and theythink nothing of taking advantage of others to get what theywant. Theythink this is the "American Way".
